Pressure Closure for Beverage and Food Containers

ABSTRACT

A container and its airtight closure. By crimping an open container a new rim ( 050 ) is made having two salient outer ( 05 B) and inner ( 05 A) sides and planes ( 05 A,  05 B) where a gasket ( 24 ) can be accommodated. A typical airtight closure for the open container is made up of a protecting cover ( 2 ) joined to an outer rim ( 5 ) that accommodates with precision to the brim of the can ( 05 ). It has also an internal rim ( 4 ) which along with the outer rim ( 5 ) forms a slot ( 070 ) on the protecting lid, which has an inner ( 5 A) and outer ( 5 B) sides which conform to the inner and outer sides ( 05 A) and ( 05 B) of the sealed brim. The closing surface ( 2 ) has an inverted arch-like ( 25 ) shape, which by mechanical action and gas pressure of the content, renders an airtight seal on the contact planes ( 2 B,  05 B).

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to: 1) an airtight closure installed by pressureto protect containers closed by double seam, and open with the fingers,2) a container and its airtight closure by pressure that is opened withthe fingers and replaces the depressed double seam closure. Theinvention prevents that a depressed closure like the aluminum can forbeverages, collects dirt during transport and storage. It also improvesthe esthetics and can be used as an advertising media. The lid isinstalled by the manufacturer.

2. State of the Art

Laminate metal containers like the aluminum can for beverages are closedby doubled seaming the closure to the container which creates adepressed sealing surface where dirt is accumulated that gets in contactwith the product when emptying or drinking. This makes it prone tocontaminate product and consumer, which has been caused of deceased. Theinvention proposes an airtight closure that protects from dirtcontainers with depressed closures. Although, the proposed lid is of lowcost, it is additional to the can as it is used currently. The inventionproposes additionally a modified container which is hermetically closedby a lid derived from the first, which closes by pressure and is openedwithout tools. The invention can be used with current containers, can bemade and installed with the same machines, reduces cost and preventscontamination.

It is an object of the invention to provide a hermetic protecting lid ontop of depressed closures of containers of beverages and food, machineinstalled by pressure after the filling, which is opened with no toolsand closes the container after being opened. This lid can be printed,stamped and engraved and has a space for advertising inserts.

A second object of the invention is to provide a container that can behermetically closed by pressure with a closure, which can be opened withno tools.

A third object of the invention is to provide an airtight closure bypressure, machine installed after the filling by the manufacturer of thebeverage, that can be opened without tools, protects the contaminablesurfaces from contacting the product when emptying and consuming andcloses the container of the second object of the invention.

A fourth object of the invention is to provide a sealable receptacle forspecial inserts that can be accommodated in the space created in theaforementioned lids.

DESCRIPTION OF CURRENT ART

The double seam closure requires room for the internal roll, whichleaves a depressed surface exposed to dirt and contamination, which candisseminate diseases. Although food and beverages are packed by themanufacturer with asepsis, this condition is lost during transport andstorage, which can become a hazard for consumers. Manufacturers ofcanned beverages and food do not have an efficient and cost effectivemean to protect the exposed areas of the container. They use for examplean aluminum foil, which is fragile and is not airtight (Kronseder,US2004134913). They use also plastic wrappings all over the cans.

In the art there are various closures proposed to protect the containeronce it has been opened, to facilitate consumption and protecting forforeign elements, as in CA2262341 that is closed by pressure usingL-shaped hooks. (Reusable Beverage Can Cap Robinson Kenton I). It alsoallows inserting a low disk-like in the inside rim of the can. Telmon(US2004226951 Pressure-applied lid for canned beverages) this lid can beopened by pulling on a handle and includes tear-off lines indicatingthat the lid has been opened.

The invention differs from the former ones on several traits. Forexample, this invention in besides using two rings that create a slotwhere the edge of the container inserts, the inner and outer sides ofthe brim have the same shape of this edge to secure hermeticity,essential for sanitary protection, still having the condition of beingopened with the fingers. The lid of the invention is airtight even whenthe lower portion of this ring is torn off for security purposes. Thelids of the invention have been designed to be machine installed by themanufacturer of the beverage or food, while most of the ones cited aredesigned to be put on by the consumer. The art cited does not include aring with a salient or slot to retain inserts within the lid or areceptacle that can accommodate in such space. The space between theprotecting cover and the upper surface of the container closure isvariable and can take a variety of forms, depending on the advertisingpurposes. The invention includes several security means to show whetherthe lid was opened.

As for closure systems for containers using pressure the review of theart shows Uhlig (U.S. Pat. No. 4,487,326, Carbonate beverage package)proposing a plastic closure by pressure for a container speciallydesigned. Hancocks (EP761557, Wide-mouthed pressurisable beveragecontainer) proposes a threaded closure which withstands the internalpressure in the container. The present invention differs from the oneslisted in that the invention is designed to be used on currentcontainers, with modifications made and installed with the sameequipment used for double seaming.

SUMMARY OF THE INVENTION

The airtight closure of containers like the beverage can is achievedwith a design that takes advantage of some of its traits. Essentiallythe closure is made up of a protecting cover (2) affixed on top of theclosed container by its depressed surface (02), unitfied to an outer rim(5) that accommodates with precision to the brim of the can (5). It hasalso an internal rim (4) which along with the outer rim (5) forms a slot(7) on the protecting lid. The protecting covering (2) prolongs downsideforming a protecting skirt (8) adapted to the form of the container tobe protected.

The lid is secure by pressure, with no glues, and covers and seals theupper part and the sides of the container that can be in contact withthe consumer's lips. It has also a salient rim (3) in the internal sideof the protecting cover to engage by pressure en groove (3A) of thecontainer. The function of these three elements (3, 4 and 5) is tosecure, without glue, the protecting lid to the upper part of thecontainer, acting individually or cooperating.

The design also embodies an internal security ring (10) which is anextension of the internal rim (5) and a hinge (9). It also includesstack rims (6). The internal rim (4) has at least one salient rim orslot (4B). Forming part of the outer rim (5) the protecting lid has aninner surface (5B) with shape and dimensions matching the ones in thesalient outer rim (05B) to secure airtight seal, in addition to a plane(05B″) that keeps it in position. The protecting skirt (8) has a sealingedge (8B).

It is possible to make a closure to replace the depressed one, avoidingcontamination. The container of the invention does not have thedepressed surface (02) and its brim (05) is salient in both sides (05A,05B). This container has a closure derived from the former, which in itsrim (5) has an internal salient (5A) with shape and dimensions matchingthe ones of the salient contour of the internal side of the brim (05A)to secure airtight seal. The surface (2) is an inverted arch like whoseimpost (05A′) contacts the plane (05A″), keeping the lid in position.The container and its closure are made with the equipment used to makethe aluminum can.

DETAILED DESCRIPTION OF THE INVENTION

The following embodiments broadly illustrate the invention but do notlimit its scope:

Referring in general to FIGS. 1 to 6 the inventive closure is made up ofa protecting cover (2) affixed on top of the closed container by itsdepressed surface (02), join to an outer rim (5) that accommodates withprecision to the brim of the can (05). It has also an internal rim (4)which along with the outer rim (5) forms a slot (7) on the protectinglid. The protecting cover (2) prolongs downside forming a protectingskirt (8) adapted to the form of the container to be protected, that hasa sealing edge (8B), also useful when the closure is installed.

The lid snaps on a typical aluminum can, and covers and seals the upperpart and the sides of the container that can be in contact with theproduct and the consumer's lips. It has also a salient rim (3) in theinternal side of the protecting cover to engage by pressure in groove(3A) of the container. The function of these three elements (3, 4 and 5)is to secure the protecting lid to the upper part of the container,acting individually or cooperating.

The closure also embodies an internal security ring (10) which is anextension of the internal rim (5) and a hinge (9) to discard the lidalong with the container. This security ring (10) can be located invarious places. It also includes stack rims (6). The internal rim (4)has at least one salient rim or slot (4B) to keep in place advertisinginserts in the void (11) created between the depressed surface (02) andthe protecting cover (2), which also has the salient rim or slot (3,3B). These rims (3B. 4B) are also useful to secure a sealable receptacle(1) that can be inserted in the void (11).

The outer rim (5) has an inner surface (5B) with shape and dimensionsmatching the ones in the salient outer rim (05B) of the container tosecure airtight seal, in addition to an engaging plane (05B″) that keepsit in position.

In this invention it is essential that airtightness is achieved with theprecise matching of the salient contours of the brim of the can and notjust with a L-shaped hook that snaps the closure in. This is used tosupport and to retain, but not to seal, since it can be torn off as partof the inner security rim.

FIG. 1 depicts the perspective and cross section of the closure with theprotecting cover (2) the salient rim (3), inner rim (4), the outer rim(5) and the slot (7), that accommodates with precision to the brim ofthe can (05) to secure the closure by pressure and renders gas-tightsealing. It shows also the protecting skirt (8) which extends downsideadopting the form of the container to be protected. As indicated, thepurpose of these elements is to secure the protecting lid to the upperpart of the container, acting individually or cooperating, to render asubstantially airtight sealing and to cover the upper part and sides ofthe container to prevent contamination of these surfaces that can be incontact with the consumer's lips or the product when drinking oremptying.

FIG. 1. also shows the inner security ring (10) that tears off andindicates whether the lid has been previously opened. There are severalsuitable places and ways to provide the closure with a security device.This rim is also useful to keep the closure linked to the container bythe hinge (9) when discarded. This figure also depicts the flange (12)when it is used the current security system, that will be describedlater on.

It also shows the stacking rims (6) which should be preferably nocontiguous to prevent dirt and water to build up on the protectingcover. The figure depicts the outer rim (5) the inner surface (5B) withshape and dimensions matching the ones on the salient outer rim (05B) ofthe container to secure airtight seal, and the engaging plane (05B″).

The protected void (11) can hold advertising inserts hold in place withthe salient rim or slot (4B) of the inner rim (4) or with (3B) of therim (3). In this invention this space is of variable height (15) sincethe protecting cover (2) can have different heights with respect to theplane on the brim of the container, allowing for inserts of varyingdimensions. As mentioned these rims or grooves (3B, 4B) are also usefulto secure a sealable receptacle (1) that can be inserted in the void(11).

FIG. 2 depicts the perspective and cross section of a typical metalbeverage container with the opening handle (01), the depressed cover(02), the groove (03) and the seamed brim (05) with its inner side(05A), the outer one (05B) and its inferior engaging planes (05A″) and(05B″), the sloped surface (08) and the body of the container (09).

FIG. 3 depicts the perspective and cross section of a typical closureassembled to a typical container showing the elements describedpreviously, including the receptacle for inserts whose descriptionfollows.

FIG. 4 depicts the perspective and cross section of a typical receptacle(1) for special inserts. Although the inserts can be placed directly inthe protected void (11) and hold in place by the brims or grooves (4B,3B) some can be taken from the closure with this protection to be usedlater on. The sealable receptacle (1) is made up of a flat ring (16) toglue on the sealing cover (17) by any suitable mean and material; ofgroves and brims (14) matching the grooves and brims (4B, 3B). Theseelements have shapes to conform to the contours and dimensions of eachcontainer and to the height of the protecting cover (2), in such a wayfor the receptacle to take the shape of void (11) of the closure.

FIG. 5 depicts the perspective and cross section of other options of theprotecting cover (2), including a dome that allows stacking (FIG. 5 a).However, these surfaces can vary in shape and dimensions, according toadvertising purposes. In its simplest embodiment (FIG. 5 b) theprotecting closure of this invention does not have the security ring(10), the flange (12) to remove a security band, the rim (3), theprotecting skirt (8) or the stack rims (6). Others may be designed tocreate maximum room but not interfering with dispensing machines, othersnot interfering the stacking, like the dome of FIG. 5 a, others with nolimit of form, to meet advertising purposes. Like wise, the sealablereceptacles will have shapes matching every closure design.

FIG. 6 shows examples of uses for the closure like to carry a pluralnumber of containers (F6 a) by means (23) that are part of itsfabrication and that can be removed from the lids, with holes (20) toinsert a handle (21, 22). A device to collect advertising lids (FIG. 6b) and when used to assemble and advertising object (FIG. 6 c)

FIG. 7 depicts the perspective and cross section of a typical opencontainer, without the depressed surface (02) to which, by double seam,a new rim (050) is made having two salient outer (05B) and inner (05 A)sides and planes (05A″, 05B″) where a gasket (24′) can be accommodated.The geometry of the brim and of the surfaces (05A, 05B) cooperates withthe corresponding one in the groove (070) of the closure of theinvention.

The gasket (24′) is to secure airtight contact between the planes (05 A″y 05B″) and the corresponding ones on the lid (5 A′ y 5B′), must be ofmaterial that meets norms and can be a ring put on when seaming orperhaps more practically, the seaming is made with a co-extrude foil onone or both sides with a polymer, as is done currently, which gives morevolume to the brim and more contacting area. In this case the brim ofthe container has a finishing that prevents direct contact of the lipswith the metal. Neither the salient sides or its downside longitude haveto be symmetrical, one can protrude more and be longer than the otherand have different geometries on their surfaces. What is essential isthat they match with the corresponding ones on the closure.

FIG. 8 depicts the perspective and cross section of a typical airtightclosure for the open container of the invention. This closure has thesame traits of the protecting lid already described (FIGS. 1 to 6), towhich are added: the groove (070) has an inner (5A) and outer (5B) sideswhich conform to the inner and outer sides (05A) and (05B) of the seamedbrim. The geometry of the groove (070) and the surfaces of the sides (5A′, 5B′) cooperate with their similar (05 A″ y 05B″) in the seamed brimof the open container. If the container is made of plastics or glass thesalient inner and outer sides are made on the mold and will require agasket only on the closure when this is metallic.

For an embodiment for a metal closure these elements prolong down side,forming an entrance (2A) and a plane (2B) which contacts the inner side(05B″) of the rim. This plane has a gasket (24′) to secure airtightsealing. The closing surface (2′) has an inverted arch like (25) shape,which by mechanical action and gas pressure of the content, rendersairtight sealing on the contact planes (2B, 05B″). As it is known in theart, the alloy, rays and rings on the surface, enhance the capacity towithstand pressure and closing. The concavity is covered with a lid (2E)that accommodates in the entrance (2A), or is glued on the surface (2C).It can have a flange (2D) to remove it. This can also be accomplishedwith pre-cuts on (2E).

The grove (070) snaps on the rim (050) of the container and then thecrimping rolls press and stamp their shapes to the rim and to theclosure (FIG. 7 b) to complete the close up. The groove of the closure(070) can be slightly opened before it is snapped on (FIG. 7 c) havingthe final pressure with the rolls. The brim of plastic closures can alsobe pressed with rolls, with or without heat, thermo fusion or laser aretechniques applied for similar purposes. In each case it will be decidedhow much pressure or heat are convenient, and still removing the closurewith out undue difficulty.

Several convenient arch-like shapes can be used. FIGS. 9C, D and Edepict various possible shapes for a metal closure. FIG. 8B depicts across section and perspective of a plastic closure which prolongsinternally downside until reaching the conical part of the container,which becomes a second support plane.

These brims (5A and 5B) have also security rings (10) that tear off whenthe lid is opened, as the ones described, to protect the integrity ofthe product and of the insert. Besides this security mean of theinventive closure, it is possible to use external means known in theart, remove by pulling a flange (12). It is also viable to make pre cutson the metal material or breaking points on other materials, to tearthem off from the closure and remaining affixed to the container. As itis known in the art, it is possible to provide a hinge (9) to keep theclosure affixed to the container.

For containers withstanding internal pressure the inventive closure canbe of two types:

1. The arch like section is integral and a flat surface is added (FIG.8), and

2. The flat surface is integral and the arch like section is added.

In a second embodiment no shown, the flat surface (2′) is an integralpart of the closure and the entrance (2A) is in the inside to receivethe arch like section (25), achieving the same effect of gas pressure.In both modalities the void (11) between the arch like section (25) andthe flat surface (2E) can accommodate advertising inserts or a sealablereceptacle (1).

The airtight closure of the invention meets standard norms for this typeof containers, like gas pressure, keeping airtightness under differentcircumstances, normal mishandling in transport and of the final user,droppings, daily differences in temperature and atmospheric pressure. Italso provides proper security for the integrity of the product and theadvertising inserts. There are several means to meet these norms: designand construction to transmitting the tensions like convexities, ringsand rays, appropriate thickness and complementing use of heat, pressureand laser.

FIG. 8 depicts also a valve (30) installed on the surface of the closurein a convenient place and whose function is to liberate gases incontrolled way to reduce pressure before opening, if needed, and to fillin the container previously closed, modifying the current filling insystem. 49, 239

FIG. 9 shows the perspective and cross section of the closure assembledon the container, with the elements described previously.

An expert in the art will know that this airtight closure can be usedfor containers not withstanding gas internal pressure. For thesecontainers the design is similar minimizing or not including the archlike shape, and hermeticity is achieved with grabs and pressure of theelements described.

Construction

The protecting lid is made separately with any material suitable formolding, for each type and dimensions of container. The airtight closureis made separately of plastics, metals, composites, paper, cardboard,synthetic paper. It can also be thermo fuse (blister) on the container.Several combinations are possible: container and closure made ofaluminum, container of aluminum, plastic or glass and closure made ofplastics. When the closure is made of aluminum it is fabricated with theequipment and methods currently used for the construction of thedepressed closure.

The open container of the invention and its closure are made from anycontainer currently in use. For example, for the aluminum can issufficient to double seam a circular crown using the hook of thecontainer that is used today to double seam the depressed closure. It isconvenient that this hook bends in instead of out. This double seam ismade with the same equipment and process currently in used, adapting theform of the rolls. FIGS. 11 a, 11 b.

Installation

The closure is installed on the container with the machine and processcurrently used to double seam the depressed closure. The pressure on thebrim is made is similar to the method and machine for double seaming ofthe depressed closure to the container, giving to the rolls a convenientgeometric shape.

The process to make and install the new container and its closure, foran aluminum can is:

1. Double seam to the container a brim with salient surfaces on bothsides,

2. Made a closure with geometry conforming the one in the container, assuggested in the invention,

3. On top of a container filled in, machine install the closure bypressing, or

4. If the container has been close empty, fill in the liquid using thevalve.

For consumption

1. Verify that the container has not been previously opened

2. Open the container pushing up the lower edge of the skirt. Press downthe valve if it is necessary to alleviate excessive gas pressure withinthe container, before opening

3. Take out advertising inserts or the sealable receptacle

4. From a wide mouth container, consume part of the content and closeagain by pressing down with bare hand.

Applications

The closure of the invention can be used for any open container on whicha brim with salient on both sides can be made and whose geometry can berepeated on the closure. It can be useful to close containers of wide ornarrow mouths as tin cans, aluminum cans, and glass bottles for wines,sparkling wines, pops, beer and the like. Also for plastic bottlescurrently using threaded closures. Using appropriate materials it can beused for products heated after closing.

The invention can be used as an advertising device. Most materials usedfor construction can be printed, imprinted, stamped with colors and aresuitable for stickers. The void (11) is useful to insert advertisingobjects, like the ones used in similar means by the experts inadvertising and promotion. The sealable receptacle widens theseapplications.
